無法添加或更新子行：外鍵約束在休眠失敗

嘿我試圖插入數據到數據庫，但得到錯誤，我已經閱讀所有從stackoverflow，但無法得到我的解決方案。無法添加或更新子行：外鍵約束在休眠失敗

不能添加或更新子行，外鍵約束失敗（posexchange_order_detail，約束FK_5ed8cb725cbc40e2be44a4ab3d9外鍵（GOODS_DETAIL_ID2）參考文獻goods_detail（ID））

這裏是我的代碼

這裏的服務來創建數據

public ExchangeOrder createExchangeOrder(ExchangeOrder domain, List<ExchangeOrderDetail> details, List<BankPayment> bankPayments) { 
     ExchangeOrder newDomain = exchangeOrderDao.saveNew(domain); 
     if (domain != null) { 
      for (ExchangeOrderDetail detail : details) { 
       System.out.println("saving exchange order 2"); 
       if (d.getGoodsDetail2() != null) { 
        detail.setExchangeNumber(newDomain.getExchangeNumber()); 
        detail.setExchangeOrder(newDomain); 
        exchangeOrderDetailDao.saveNew(detail); 
       } 
      } 
      for (BankPayment bp : bankPayments) { 
       bp.setTransactionNumber(domain.getExchangeNumber()); 
       bankPaymentDao.saveNew(bp); 
      } 
     } 
     return newDomain; 
    }

謝謝你。

我看可能會造成這幾個可能的問題：

任何原因，您同時使用了@Column爲GOODS_DETAIL_ID1也是一個@ManyToOne在同一類GOODS_DETAIL_ID1列註釋的Integer？
由於@Column註釋指出goodsDetail1和goodsDetail2的值必須不爲空，但我沒有看到您在您提供的代碼中設置這些值。因此，請嘗試刪除重複的列聲明並確保
如果正在設置GoodsDetail實體，請確保在保存ExchangeOrderDetail之前保存了它們，因爲沒有明確的級聯保存正在進行。
